1.9 g; 78%		Synthesis of Compound 6bTo a flame dried 500 mL RB flask, freshly activated Mg turnings (2.4 g, 100 mmol) were added and the flask was equipped with a magnetic stir bar, an addition funnel and a reflux condenser. This set-up was degassed and flushed with argon and 10 mL of anhydrous ether was added to the flask via syringe. The bromide 3 (26.5 g, 80.47 mmol) was dissolved in anhydrous ether (50 mL) and added to the addition funnel. About 5 mL of this ether solution was added to the Mg turnings while stirring vigorously. An exothermic reaction was noticed (to confirm/accelerate the Grignard reagent formation, 5 mg of iodine was added and immediate decolorization was observed confirming the formation of the Grignard reagent) and the ether started refluxing. The rest of the solution of the bromide was added dropwise while keeping the reaction under gentle reflux by cooling the flask in water. After the completion of the addition the reaction mixture was kept at 35 C. for 1 h and then cooled in ice bath. Ethyl formate (2.68 g, 36.2 mmol) was dissolved in anhydrous ether (40 mL) and transferred to the addition funnel and added dropwise to the reaction mixture with stirring. An exothermic reaction was observed and the reaction mixture started refluxing. After the initiation of the reaction the rest of the ethereal solution of formate was quickly added as a stream and the reaction mixture was stirred for a further period of 1 h at ambient temperature. The reaction was quenched by adding 10 mL of acetone dropwise followed by ice cold water (60 mL). The reaction mixture was treated with aq. H2SO4 (10% by volume, 300 mL) until the solution became homogeneous and the layers were separated. The aq. phase was extracted with ether (2×100 mL). The combined ether layers were dried (Na2SO4) and concentrated to get the crude product which was purified by column (silica gel, 0-10% ether in hexanes) chromatography. The slightly less polar fractions were concentrated to get the formate 6a (1.9 g) and the pure product fractions were evaporated to provide the pure product 6b as a colorless oil (14.6 g, 78%).
40%; 8%		[0157] The intermediate compounds (6Z,9Z,28Z,31Z)-heptatriaconta-6,9,28,31- tetraen-19-yl formate (6) and (6Z,9Z,28Z,3 lZ)-heptatriaconta-6,9,28,3 l-tetraen-19-ol respectively identified as compounds (6) and (7) in Reaction 2 above were prepared in an oven dried 3-neck 500mL flask that was charged with Mg (0.5g, 20.83mmol, 1.37 eq.) and (one crystal) under argon. The flask was degassed on a high-vacuum line, then flushed with argon (the process was repeated four times) and then stirred at room temperature for approximately 5 minutes. Anhydrous ether (22mL) was added to this flask and the slurry stirred for approximately 10 minutes. Next, 5g (15.2mmol, 1 eq.) of compound (5) (<strong>[4102-60-7]linoleyl bromide</strong>) was added under argon (color change was observed after the addition of approximately 4.5mL of compound (5)) and the reaction stirred at room temperature. An exothermic reaction was observed after stirring for approximately 5 minutes at room temperature. Thus, the mixture was cooled using an ice-water bath for approximately 2 minutes, then the ice-bath was removed and the reaction mixture stirred at room temperature for 2 hours, resulting in an ash colored reaction mixture and not all of the Mg was consumed. The mixture was cooled to 0 C and the HC02Et (0.58 mL, 7.17mmol, 0.47 eq.) was added dropwise directly into the solution. After stirring at room temperature for 3 hours (product was observed after 1 hour by MS and TLC) the mixture was decanted and the Mg turnings washed with ether. The combined washings were diluted with ether (lOOmL), washed with 10% H2S04 (2 X 50mL), water, brine and then dried ( a2S04). The solution was filtered, concentrated and the residue purified by silica-gel column chromatography. [0158] 5-7% ether in hexanes eluted the alcohol (compound (7)) from the residue.

Yield	Reaction Conditions	Operation in experiment
86%		To a flame dried 500 mL RB flask, freshly activated 16 Mg turnings (2.4 g, 100 mmol) were added and the flask was equipped with a magnetic stir bar, an addition funnel and a reflux condenser. This set-up was degassed and flushed with argon and 10 mL of anhydrous ether was added to the flask via syringe. The bromide (13 3) (26.5 g, 80.47 mmol) was dissolved in anhydrous ether (50 mL) and added to the addition funnel. About 5 mL of this ether solution was added to the Mg turnings while stirring vigorously. An exothermic reaction was noticed (to confirm/accelerate the Grignard reagent formation, 5 mg of 17 iodine was added and immediate decolorization was observed confirming the formation of the Grignard reagent) and the ether started refluxing. The rest of the solution of the bromide was added dropwise while keeping the reaction under gentle reflux by cooling the flask in 12 water. After the completion of the addition the reaction mixture was kept at 35 C. for 1 h and then cooled in ice bath. 18 Ethyl formate (2.68 g, 36.2 mmol) was dissolved in anhydrous ether (40 mL) and transferred to the addition funnel and added dropwise to the reaction mixture with stirring. An exothermic reaction was observed and the reaction mixture started refluxing. After the initiation of the reaction the rest of the ethereal solution of formate was quickly added as a stream and the reaction mixture was stirred for a further period of 1 h at ambient temperature. The reaction was quenched by adding 10 mL of 19 acetone dropwise followed by ice cold water (60 mL). The reaction mixture was treated with aq. H2SO4 (10% by volume, 300 mL) until the solution became homogeneous and the layers were separated. The aq. phase was extracted with ether (2×100 mL). The combined ether layers were dried (Na2SO4) and concentration of the organic layer over reduced pressure provided the crude product as a mixture of required dilinoleylmethanol along with minor amounts of O-formylated product. This crude product was re-dissolved in 20 THF (100 mL) and treated with ice-cold 21 aqueous NaOH (10%) and heated at 40 C. for 18 h after which the TLC (10% ether in hexanes) showed the complete conversion of the O-formylated product to the required dilinoleylmethanol. The reaction mixture was cooled and was extracted with ether (3×100 mL) and the combined organic layers were washed with brine and dried over sodium sulfate. Filtration followed by concentration of the organic layer provided the crude product. The thus obtained crude product was purified by column chromatography using 60-120 mesh silica gel using 4% ether in hexanes. Concentration of the pure product fractions provided the pure 22 product (15.4 g, 86%) as a colorless liquid.

In a separate flask, a solution of <strong>[4102-60-7]linoleyl bromide</strong> (140 g, 425 mL) in anhydrous THF (150 mL) was prepared, and 20 mL of this solution added to the magnesium. When most of the heat had dissipated, the remainder of the bromide was added over a period of 15 minutes. Temperature was then maintained at 45 C. for 4 h. The reaction was then cooled (0 C.). Using a dropping funnel, a solution of ethyl formate (32.4 g, 438 mmol) in anhydrous THF (150 mL) was added over a 40 minute period. The reaction was stirred overnight at room temperature. The reaction was cooled to -15 C. and 5N HCl (185 mL) added slowly. The mixture was transferred to a 2 L separating funnel separated. Water (150 mL) and hexane (150 mL) were added, the mixture washed, and again the aqueous removed. The organic was washed a final time with water (150 mL) and then concentrated to a yellow oil. The yellow oil was stirred with a mixture of EtOH (210 mL), water (30 mL) and KOH (15.8 g) for 1.5 h at room temp. The EtOH was evaporated and the residue treated with hexane (50 mL). 5N HCl (200 mL) was added via dropping funnel. The organic was washed with water (2×50 mL) evaporated, dried and purified by chromatography (0-5% EtOAc in hexane, 91 g, 81%).
81%		STEP 2: Al liter REF was charged with magnesium turnings (11.1 g, 463 mmol), anhydrous THF (65 mE) and stir-bar and flushed with nitrogen. In a separate flask, a solution of <strong>[4102-60-7]linoleyl bromide</strong> (140 g, 425 mE) in anhydrous THF (150 mE) was prepared, and 20 mE of this solution added to the magnesium. When most of the heat had dissipated, the remainder of the bromide was added over a period of 15 minutes. Temperature was then maintained at 45 C. for 4 h. The reaction was then cooled (0 C.). Using a dropping thnnd, a solution of ethyl formate (32.4 g, 438 mmol) in anhydrous THF (150 mE) was added over a 40 minute period. The reaction was stirred overnight at room temperature. The reaction was cooled to -15 C. and SN HC1 (185 mE) added slowly. The mixture was transferred to a 2 E separating thnnel separated. Water (150 mE) and hexane (150 mE) were added, the mixture washed, and again the aqueous removed. The organic was washed a final time with water (150 mE) and then concentrated to a yellow oil. The yellow oil was stirred with a mixture of EtOR (210 mE), water (30 mE) and KOR (15.8 g) for 1.5 h at room temp. The EtOR was evaporated and the residue treated with hexane (50 mE). SN HC1 (200 mE) was added via dropping funnel. The organic was washed with water (2x50 mE) evaporated, dried and purified by chromatography (0-5% EtOAc in hexane, 91 g, 81%).

80%		A clean dry 200 L total glass reactor fitted with an argon inlet, a reflux condenser and a thermowell was degassed and purged with argon. The reactor was charged with 277 g (11.3 mol) of active magnesium and then 1.5 L of anhydrous ether. The reactor was again evacuated three times and purged with argon. Bromide 4 (2.5 Kg, 7.6 mol) was dissolved in 5 L of anhydrous ether under argon, 1 L of this solution was added to the reactor and then 25 mL (0.35 mol) of dibromomethane was added. The contents of the reactor were heated to 40 C. using a water bath (refluxing after foaming was observed, indicating the onset of Grignard reagent production). After initiating the reaction, the heating apparatus was removed from the reactor and the remaining 4 L of bromide was slowly added over a period of 2 hours 30 minutes while maintaining a gentle reflux of the mixture. After addition was complete, the reaction mixture was again heated to reflux (bath temperature 45 C.) for 1 hour, after which an aliquot of the reaction mixture was quenched with water and analyzed by TLC (hexane, PMA staining). This indicated complete disappearance of the starting bromide. The reaction mixture was cooled to below 10 C. using an ice bath and ethyl formateEther solution (275 mL in 4 L of ether) was added over 2 h 30 min and after addition was complete the reaction mixture was warmed to room temperature and stirred for 1 h. The reaction mixture was cooled to 10 C., acetone (1.15 L) was slowly added to the mixture and then prepared by dissolving 7 L of ice cold water and 3.4 L of sulfuric acid with 34 L of ice cold water ) 10% sulfuric acid solution were added. The product was extracted with 3 × 10 L of ether and the combined organic layers were washed with 10 L of brine and dried over sodium sulfate (2 Kg). Concentration of the organic layer under reduced pressure gave the crude product (2 Kg) as a mixture of required dilinoleyl alcohols along with traces of O-formylated product. This crude product was redissolved in THF (4 L) and loaded into a 20 L glass reactor. To this was added a NaOH solution (0.934 Kg dissolved in 8 L of ice cold water) and the contents were heated at 65 C. for 18 h and then subjected to O-formylation by TLC (10% ether in hexane) Indicating that the product was completely converted to the desired dilinoleyl methanol. The reaction mixture was cooled, extracted with ether (3 × 4 L) and the combined organic layers were washed withWashed with 5 L of brine and dried over sodium sulfate (4 Kg). After filtration, the organic layer was concentrated to give a crude product. The crude product thus obtained was purified by column chromatography using silica gel of 60-120 mesh with 4% ether in hexane. Concentration of the pure product fractions gave pure 6 (1.45 Kg, 80%) as a colorless liquid

Yield	Reaction Conditions	Operation in experiment
81%		A 1 liter RBF was charged with magnesium turnings (11.1 g, 463 mmol), anhydrous THF (65 mL) and stir-bar and flushed with nitrogen. In a separate flask, a solution of <strong>[4102-60-7]linoleyl bromide</strong> (140 g, 425 mL) in anhydrous THF (1 0 mL) was prepared, and 20 mL of this solution added to the magnesium. When most of the heat had dissipated, the remainder of the bromide was added over a period of 15 minutes. Temperature was then maintained at 45C for 4 h. The reaction was then cooled (0C). Using a dropping funnel, a solution of ethyl formate (32.4 g, 438 mmol) in anhydrous THF (150 mL) was added over a 40 minute period. The reaction was stirred overnight at room temperature. The reaction was cooled to -15C and 5N HC1 (185 mL) added slowly. The mixture was transferred to a 2 L separating funnel separated. Water (150 mL) and hexane (150 mL) were added, the mixture washed, and again the aqueous removed. The organic was washed a final time with water (150 mL) and then concentrated to a yellow oil. The yellow oil was stirred with a mixture of EtOH (210 mL), water (30 mL) and KOH (15.8 g) for 1.5 h at room temp. The EtOH was evaporated and the residue treated with hexane (50 mL). 5N HC1 (200 mL) was added via dropping funnel. The organic was washed with water (2 x 50 mL) evaporated, dried and purified by chromatography (0 - 5% EtOAc in hexane, 91 g, 81%).
11.6 g		A 250 mL three-neck reactor was purged with dry argon, into which 2.21 g (92 mmol) of activated Mg and 12 mL of anhydrous diethyl ether were added. Product 4 (20 g, 61 mmol) was dissolved in anhydrous diethyl ether (40 mL). Under the protection of argon, 8 mL of the product 4 solution was added to the reactor, together with 0.2 mL (2.8 mmol) of dibromomethane. Using a water bath, the temperature of the reaction mixture was increased to 40 C. After the start of the reaction, the heating resource was removed, and the remaining solution (32 mL) was added drop wise to the reactor within 1 hour, while maintaining a gentle reflux of the mixture. After the completion of the addition, the reaction mixture was heated to keep reflux for 1 hour. After the raw materials were completely consumed, the reaction mixture was cooled to below 10 C. using an ice-bath, in which a diethyl ether solution of ethyl formate (prepared by dissolving 2.2 mL of ethyl formate in 32 mL of diethyl ether) was added slowly. The reaction mixture was warmed to room temperature and incubated for 1 hour under stirring. Then ice-cold water (56 mL) and 10% sulfuric acid solution (prepared by dissolving 27.2 mL of sulfuric acid in 272 of ice-cold water) were added, from which the organic layers were separated. The aqueous layer was extracted with diethyl ether (3×80 mL). The combined organic layers were washed with brine solution (80 ml), dried over sodium sulfate (16 g) and filtered. The organic layer was concentrated and organic solvent was removed with a vacuum pump to obtain a crude product (a mixture of alcohols and formate). This crude product was redissolved in 100 ml of THF. To this a solution of NaOH (prepared by dissolving 7.5 g of NaOH in 150 mL of water) was added and the contents were heated to and incubated at 65 C. for 18 hours. After the completion of the reaction, the reaction mixture was cooled to room temperature and extracted with diethyl ether (3×100 mL) The combined organic layers were washed with brine solution (40 mL), dried over sodium sulfate (40 g) and filtered. The organic layer was concentrated. The thus obtained crude product was purified using a 60-120 mesh silica gel (4% ethyl ether in hexane), to obtain the pure product 6a (11.6 g, 80% yield). 1H-NMR (CDCl3, 400 MHz), delta=5.47-5.24 (m, 8H), 3.70-150 (m, 1H), 2.85-2.66 (m, 4H), 2.12-1.91 (m, 9H), 1.55-1.17 (m, 46H), 0.90-0.80 (m, 6H).
